    Unfortunately, as of today, Diho is no longer our weekly go-to restaurant for Thai food, they just increased the menu prices across the board, we noticed a number of dishes are 25% more expensive, and what we always came for were the lunch specials which are also no longer a good deal, as $14, $15 or $16 for an entree is not really "special", it just brings it to market level pricing along with the other restaurants in this plaza, which I believe are not really worth except for one. We used to overlook Diho's occasional slow service at times, or tofu that went bad and then other times when our order was wrong, we just accepted it because the prices were very reasonable, we didn't expect as much because of the value. That has now changed. With higher prices, I would expect decent service and today was not too great. We waited a while before someone even came to our table with a menu, we had to get our own pepper, had to ask for the crispy noodles- which other tables had and normally just come to the table, my food and my dish was disappointing, less specific veggies than I usually have. This will probably the last time we come to Diho for a while, we will especially miss coming to Diho for a great value, but at these prices, there are now better options with better service and food around Lake Forest.

    Pad Thai Lunch Special with Salad
    Edith M.

    Delicious food here! They offer both Chinese and Thai and both menus are outstanding. My favorite thing to order is their chicken pad Thai. It is one of the best I've tasted and I love to ask for extra peanuts and no spice. Then ask for their chili oil. Yum! They have a great lunch menu that comes with salad or soup. Truly a great place to dine or takeout! Must try this place. Also, it's worth noting that their staff is incredibly friendly and they always make sure you get great service while dining here. [[HIGHLIGHT]]Inside is nice, clean and the vibe is casual.[[ENDHIGHLIGHT]] Must try spot!

    Drunken noodles
    Tammy S.

    The plaza that this restaurant is located in has many options. The other restaurant that we meant to go to was closed so we decided tk come here for lunch instead. I ordered pad thai from the lunch special menu and my friend ordered the drunken noodles. My pad thai was delicious and I love the peanuts that come with it. Drunken noodles were served on a bed of lettuce. Very satisfied with the quantity that is served. Salad came first. Then the entree. The pad thai is one of the best pad thais that I've had. Part of it is because I'm partial to the amount of peanuts that is served with it. My friend was a little disappointed with the limited drink options. But overall I would come back to visit and order the pad thai again.

    Pad Se-Iew Lunch Special with fried tofu
    Lucy H.

    They have the best lunch specials in town. The food is always piping hot, generously portioned, and consistent. My go to is the pad see ew with fried tofu, with generous amounts of their addictive chili sauce and pickled chilis in vinegar. Their drunken noodles, Panang curry, pineapple fried rice, pad thai, squid in Thai basil sauce, are all tried and true. On Mondays and Wednesdays they serve their hot and sour soup during lunch. Did I mention their amazing tom yum soup?

    Insane giant menu since Diho Siam seems to have two full sized menus, one for Thai and the other for Chinese cuisine. I had lunch there with a friend and I ordered the drunken noodles with pork. She ordered the sauteed ginger mushroom trio with pork. Both dishes were very good tasting. Pleasantly surprised by the portion size for the noodles. I liked it so much I went back the next day to order takeout. The ginger mushroom trio again, mushroom chicken, red curry with pork, and twice cooked pork. Once again, I was pleased to note the generous portions, this time for the dinner entrees. Standouts were the ginger mushroom trio and twice cooked pork. It's actually interesting that the twice cooked pork tasted nothing like classic twice cooked pork, didn't use the same ingredients such as pork belly or dried bean curd but was a tasty dish nonetheless. Sadly though, the mushroom chicken, which also did not follow the classic recipe, did not taste as good. It really was more of an overcooked veggie chicken stir fry. The red curry was also disappointing, very sweet and not much flavor. So, a hit or miss with half the dishes. The service was very friendly both times. Nice that they give you white rice at no extra charge. Menu states brown rice available for a couple bucks more. [[HIGHLIGHT]]Oh ambiance is nice for the inside of the restaurant, looks fresh and recently renovated.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]However, the only restroom available requires a trip through the kitchen to the very back. Seems like a health code violation idk. Still weird either way.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]My friend who has worked in restaurants noted that it made her feel like she worked there.[[ENDHIGHLIGHT]] Generous portions but that's only nice when you like the dish you ordered.

    Papaya Som Tum Salad - tasteless
    Elle J.

    Just terrible. Their other location is way better. I ordered online which is easy and decided to try this location for the sake of comparison. They have pretty affordable lunch specials, and I'm all about a good deal! Papaya salad: tasteless. I asked for spicy and there was zero spice. Totally not worth the $12 or so. Pad Thai: I ordered veggie and they gave me chicken. My order was a to go order so of course I was far away and couldn't get the order fixed. Honestly this shopping center has lots of options for food and there is zero reason to go here. Next time I'll try the sushi place or the Vietnamese place. Diho won't be getting another penny from me. I will say they have fair prices (when you can eat the food) and the portions are good.

    Best of the best noodles ever!!!
    Noah L.

    Best of the best place to eat at, in the amazing OC! Becky who works there, is a true employee, that truly understands people's dietary needs and allergies too! And makes it the best of the best and most comfortable experience ever! She is truly a blessing to everyone!!!! 100/100, for worlds best service ever!!!

    Table

    We absolutely love the food here, but there is an abusive server named Dang who is loud and obnoxious and intimidating to not only the servers, but to customers! I am horrified that Management does not do something about this evil woman. She is literally driving people away. We walk by and peek in the window to see if the sweetest waitress Becky is there, but if we see Dang we leave.

    Thank you Nina for your wonderful service! We came in in a rush because we had to get to a movie and Nina immediately took our order, had the cooks rush it, and brought it out within 10 minutes. The food was amazing, [[HIGHLIGHT]]the restaurant was clean,[[ENDHIGHLIGHT]] and [[HIGHLIGHT]]they even had fresh flowers at each table which was such a nice touch!![[ENDHIGHLIGHT]] Make this your next Thai try in OC. It was amazing!!!

    Fresh roses on each table

    Ty Yelp community for steering us in the right direction! We drove in from Vegas and skipping lunch we were ready to grub! This place is in a shopping center right across from our hotel. The plaza is loaded with restaurants. We did not regret our choice. We were warmly greeted and sat quickly. We ordered the Chicken Pad Thai, crispy egg rolls, Beef salad and Mixed Veggie with Shrimp. Told you we were hungry What did we like ....EVERYTHING! I ate the salad by myself. The meat was pretty lean and well cooked. Salad was very fresh and lightly dressed. The veggies in my stir fry with shrimp were cooked to perfection and they even removed the shrimp tails for you. Not drowning in sauce which I appreciate a lot. My husband polished off the Pad Thai which I didn't try. But he thoroughly enjoyed it. I had a bite of one of the egg rolls and was also fresh and flavorful. Not overly greasy. We were so pleased with all of our selections. Service was great, restaurant was very clean. We were the only ones dining in and our server was cleaning non stop when she wasn't waiting on us. This place does a ton of takeout orders, even though we were the only ones in the restaurant people were coming and going the entire time picking up food. When we are in town, we will definitely hit this place up again !

    Chilies and Thai Basil Lunch Special with Pork (Pad Kra Prao)
    Anita M.

    My coworkers have honestly been talking about this place for quiteeeee some time now. At least the last year or two haha. And, I've never tried Diho Siam until today. They were raving about the Thai Fried Rice that it was the best fried rice they've ever had. I actually went with the Pad Kra Prao with Pork as my protein option. It was a bit different than what I expected - I thought it would be served with ground pork instead of actual pork slices. But, that wasn't a big deal. Anyways - now I know why they kept raving about this place. My Pad Kra Prao dish - fresh basil flavor and spice in every bite. I ordered the lunch special and finished every last drop of food - because it was that good. It came with a side salad with your choice of dressing (Peanut, Spicy Lime or Creamy Mustard), your choice of rice (Jasmine or Brown) and choice of protein. I went with Jasmine rice and Spicy Lime dressing and oh. my. god. Yeah, it was all super delicious. I want to mention, we placed our order online for pickup and the food was pretty much ready by the time shown on their website after we placed the order. I also like that they send you a text when your food is ready too. The staff were all very friendly and quick to assist. [[HIGHLIGHT]]Their dining area is small, but has plenty of space for comfort.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]They also have an outdoor seating area for those of you who are interested in outdoor seating.[[ENDHIGHLIGHT]] The only difference I noticed is that if you dine in, you are served with crunchy noodles as a starter - and if you order take out, you don't get the crunchy noodles. Anyways! I had such a great experience today with Diho Siam, and I absolutely can't wait to try more of their dishes!

    It's good Thai food. It's good ingredients fresh, they are kind. They have a dish called.Hormok…read morepalay that I never had before and I really like it. I don't know how to describe what it tastes like, but it's kind of like a seafood curry with spinach and a bright rainbow curry. Pad woon soon was good too. And pad see ewe. However, I had a major disappointment Last night. I ordered a Tom kha goong soup that cost $17. Most places sell the soup for like 5-10 dollars so I'm thinking $18 is expensive that has got to be some dinner portion soup so it didn't make sense when it asked me if I wanted a large for seven dollars more, I'm thinking that that's probably a portion for a family. But it's cold and it's raining and I wanted to sip on something warm. They sent me the tiniest cup of soup. think when you go to a restaurant and they ask you if you want a cup of soup for three dollars or a bowl of soup for five dollars. I got a cup of soup. think when you go to a Japanese restaurant and they give you a small little miso soup with your meal. That's how much soup I got for $18. There were two slices of tomatoes in there a a couple mushrooms and a 2 piece of shrimp. This upset me so much because I spent so much money and was expecting some food. I politely called the restaurant and spoke to them about it and they said that they were very sorry but it's expensive because DoorDash charges 30% of the price. Which I understand, and I expect to pay more to have something delivered, but it was still very expensive for what I got, and in the end, it wouldn't have cost them much to give a large portion, and they should be more mindful about balancing what the customer is getting with their profits. Which they totally deserve their profits. It would be much more reasonable if the small was $6 and the large was $12. If that was the small I can imagine that the $25 large portion probably should've been offered as the small portion. Just writing that out upsets me so much have you ever spent $25 for a soup before?

I would suggest getting it a bit spicy/with more Thai curry. Their crab and Thai fried rice is also a hit. Their massaman curry is flavourful and not too hot. You can always add more spice if you want. My favourite noodle dishes are the Pad thai (so yummy and not dry), pad kee mao (love the Thai basil), and pad wood sen. I have ordered the chowmein, it wasn't the best or my favourite, this dish didn't really taste "Thai" at all and I would not order it again, but it does not affect my opinion of this place. The people are friendly and food is ready despite them usually being busy. Don't forget to ask for chili in vinegar - these are a yummy addition to your food.

That was last night - it's morning and I'm still thinking about the yummy flavors in my mouth! The spring rolls were good - well wrapped and filled with a perfectly made peanut sauce to dip it in. The bamboo shoots dish came with a plethora of vegetables and was mildly to moderately spicy in a good way. My favorites were definitely the beef satay which was cool to perfection and the pad Thai - very well done - and I've been eating at different Thai places since I was a teenager! The noodles were on point with the texture, the flavor was saturated throughout every bite, so yummy! I did not try the pad see ew but it looked really good.

One of my favorite things to pair with our meal is their spice rack. If you are able to handle a bit of heat, ask for it and introduce the pickle chili to your dish. It elevates flavor with contrast quite well. Pad See Ew and Crab fried rice is what we ordered. The first visit had beef salad which paired great with the rest of the meal. Overall, stop by this location for good eats. FYI, parking can be tricky so be mindful about peak hours and carpool.

She confirmed that it was. While I have not dined at all OC Thai restaurants to compare, they did a great job here and I would come back. My Spicy eggplant with chicken and brown rice was excellent. The portion size was above average which is critical for this guy that burns through food like a Ford F350 burns through gasoline. They gave and adequate amount of veggies (and you cannot have too many veggies in this dish especially peppers) and a good portion of chicken. You choose spice level on a scale of 1 to 10. I picked 3 as a guess and would not go much higher than that next time. Their brown rice is incredible--you will not find better anywhere. Service is efficient, respectful but no time to sit at your table and chat with you. One Asian woman was serving the entire restaurant and the pickups and did a great job. She was as efficient as 3 teens combined at any retail store. LOL But don't come here if you are in a mad rush. I really liked the atmosphere here. While the place in general could use a deep cleaning during their closed day I really liked the atmosphere inside which they kept cooler on a hot day (bring an extra shirt or jacket). Good place for dining alone, friends meal, family, date night or pre-romantic dinner. Everyone will feel comfortable here. There is no Valet, but a large parking lot of free and easy parking.
