I've been to Tail and Fin 3 or 4 times now and it is one of my fav sushi burrito places around town!! The staff are always extremely friendly and understanding of my allergies (can't eat shellfish so they wash knives and cutting boards real quick).
The restaurant itself is modern & trendy. It's very clean looking, which I've been to some that just don't feel that way.
Anyway, I always build my own bowl (usually half salad, half rice) with ahi tuna and a variety of veggies. They do charge extra for avocado, mango, pineapple, etc. Sometimes I've found myself wishing they had more variety of veggie toppings, but I also don't know what else I'd want. I avoid the creamy dressings, so I can't speak to those, but the other dressings are pretty tasty!
Overall, I love Tail and Fin! I'll definitely continue going back!
