If you're going to Julio's and are not drinking, you are doing it wrong.
Julio's Barrio is a great place to go to enjoy some drinks along with some standard Mexican fare. The only reason in my mind to go is to drink ridiculous "bull dogs" which are margaritas with shots and a beer tipped into them. The novelty of this drink is quite fun and they end up being pretty tasty. Don't expect the prices to be cheap or the service to be that fast as I have almost always had to wait to even get a table. The food is alright but I believe it is quite over priced.
Go for the bull dogs, or don't go at all.
