    Tempeh Burger (+ 1 chunk of fish & chips)
    Jill H.

    Avos is a great place for a casual meal & live music venue. Catch a local band jamming on a Friday night and on the summer soak up the fresh air on the outdoor patio. First time back in a while and not disappointed. Food is good - I enjoy their tempeh burger which comes with standard fixings and plenty of fries. My husband got the Friday night only fish and chips. I sampled a few bites and thought they were tasty, too. Coupled with beer and cider from the bar and we were all set to enjoy the evening with local band Orchid Wave! It's fast casual style service. Order up front and they'll give you a number and bring out your food. No complaints. Bartender and employees were all helpful and friendly.

    As an engineer, the restaurant's name stuck out to me right away (The number of units in one mole of any substance is called Avogadro's number or Avogadro's constant). I just knew I needed to check this restaurant, bar, music venue out. There just happened to be a blues band playing that day too! First off, the atmosphere of the place is really neat with a spacious and cool interior and also spacious and well decorated outdoors area. Plenty of space here to hang out! The food was amazing both in terms of price and taste. I was very surprised at the size of the sandwich for $13. I would highly recommend the Joe's Sandwich if you are a fan of cream cheese.

    Philly Cheese Steak Sandwich

    Great location near campus while moving our daughter in at CSU. There were four of us and we each had a different sandwich. The sandwiches were large with soft yummy bread. We ordered the Philly Cheesesteak, Italian, Parmesan Sub and the Joe's. I paid extra to get homemade onion rings, and they were worth the price. Others in my party had side salads and they were fresh and large. We also tried a cookie that was the size of a small plate. Next time we plan to try one of their shakes. They have as many vegetarian options as they do meat. [[HIGHLIGHT]]The location is quite large with plenty of seating inside or out.[[ENDHIGHLIGHT]] Orders are taken at the counter and then you do have to bus your own table. Prices were fair. Will definitely try again!

    I've been here a handful of times for drinks at the bar and to enjoy the patio, but this was the first time getting food. I'd looked at the menu beforehand, but that still didn't prepare me for the specials they had written on the boards and on the screens above the order counter when we arrived! I was torn between the falafel, the cheesesteak and the special of the day - the chipotle black bean burger. After asking the cashier/server's recommendation, I went with the black bean burger (she was vegetarian, so that helped limit the options). My husband got Joe's Sub and took our number sign, I grabbed a can of kombucha and we went to the patio to enjoy the afternoon. We snagged a spot in the back corner and a few minutes later, our food was brought out to us. The pasta salad I got as a side (included in the price) was delicious! Creamy without being heavy, and a nice amount of salt from the diced olives. The chipotle burger left something to be desired - a generous amount of avocado, bright red fresh tomatoes, sweet white onions, but the patty was pretty mushy and disappointing. I'm fairly certain I've purchased the same patties at Costco. It also needed some extra crunch - I stole some of my hubby's lettuce to balance it out. My husband loved his sub! The bread was nice and soft and it was STUFFED full of turkey, lettuce, tomato, onion, cream cheese, bacon and avocado. I'd definitely get this sandwich next time I go! He begrudgingly offered me a few bites before demolishing the rest of it. A beautiful patio, helpful, kind and quick service, and some delicious entrees for a relatively cheap price! We wish we'd enjoyed this all summer before the college students come back, but we'll be back anyway!

    Man, what a fun little hole in the wall! We came here to see a Grateful Dead cover band and got a couple sandwiches to go with us. I got the roast beef which was good, but the Philly cheesesteak was the real winner. The live music was awesome! Wish there were more fun spots like this. Oh, we also got the dairy free ice cream. Surprisingly delicious! Wouldn't take it over real ice cream, but still dang good.

    Avogadro's Number is so much more than just a sandwich shop. They are conscious about those who are vegan and vegetarian, while still serving up tasty food. I knew I had to try this place based on the fun and wacky pictures I saw on here. It's something amazing to see in person and a great way to decorate a restaurant and make it unique. This is a walk up and order establishment and I felt no rush to order. All the sandwiches and pairings sounded excellent and I liked that they had items that I was not familiar with like tempeh. At first, I thought the restaurant was very small, but soon realized that they have a big show room where they host concerts and such. There is also a big patio in the back of the restaurant. All you have to do is follow the restroom sign and it will lead you right to it. That's where I found majority of the people sitting and biding their time. I had the mogul sandwich with fries and wow the sandwich was good. The bread was soft and there was lots of turkey and other fillings inside. It definitely had a unique flavor and was very filling as I couldn't finish it. My mom and sister got the french dip which they said was delicious. The only negative I can find is that they made 3 french dips instead of the mogul sandwich I ordered so I had to wait a bit longer for them to get that made. However, it was definitely worth the wait! Overall, I would love to come back here to witness the concert scene and patio and try more of the wonderful food!

    2.5, edging down to 2 stars…read more Not the best food experience I've ever had. They're rated really high -- actually one of the highest-rated restaurants in Fort Collins -- and from a food perspective I don't really understand why. Sliders with sweet potato fries -- fine, nothing extraordinary. Potato éclairs -- . It was really just mashed potatoes with some topping on it. I honestly didn't even finish it. Mountain oysters -- huge letdown. They came out so overcooked they were basically crunchier than potato chips, with the batter crumbling off. I've never had them before, so I didn't get a good representation of how they're supposed to be -- these were just super-cooked batter. On the space: we ended up sitting in three different spots to eat. We went outside by the street first -- super loud, and people were smoking, so we headed back in. The open spot inside was right under the AC and about forty degrees, so we moved to the back area. The back was fine -- covered -- but pretty dirty, with mop buckets and clutter sitting around. The one drink I had was a good value since we were there at happy hour -- some kind of fruity whiskey drink. It was fine, but nothing I'd seek out again. I hate to give such a friendly place a bad review. It'd be a really great spot if you're a college student who wants some cheap bites and a drink -- but honestly it's just bar food, and the ceiling is probably a 4 on a really good day. I wouldn't get excited to head down there, and parking is a bit of a hassle too. Would recommend only if you're after very cheap eats in that area -- check them out for happy hour. But I would not return.

The acoustics were good and the venue has two bar stations one on the upper deck and another on the lower. The foyer provides ample room for band merch.

    Went to see a concert here last night; quite the unique experience! Most people have to be shuttled…read moreup for concerts as the parking is very limited. Honestly the road going up is pretty curvy and definitely dark after the sun sets, so I'm super glad we had the shuttle. The outside deck for dinner has a great ambiance right there on the river. However, the inside bar and eating area felt like a greenhouse (albeit, we've been suffering from 100+ temps for awhile now). During concerts, they don't have their indoor bathrooms available; only the use of porter poties outside, but I will say they were nicer/cleaner than I expected. They had plenty of bars open during the concert, so there was never really much of a line, which was great! The space is in the middle of a canyon right by the river and a very unique and exclusive experience that you don't see every day. People sat in the astroturf beforehand and between sets, but everyone stood/danced during the show. There aren't many seats - just in the VIP areas. Certainly an overall cool experience!

    Venue and location is great…read more Bar food and bar service is absolutely subpar at best. For being a bar their service is the slowest I've ever seen. Either hire more bartenders, or hire competent ones that can multi task. Their food is inconsistent and taste cheap. Burgers taste like frozen patties from Costco. Fries were cold and almost soggy. Onion rings, decent. I'd recommend the venue, but don't come hungry or thirsty.
