The girl asked a question. If you're going to be smart and not give her an actual answer then don't bother responding.
Huston's and roadhouse have all sorts of drinks. Anything you can think of they will be able to make. What is good depends on what kind of drinks you like. I would just bare in mind that "cocktails" are going to come at a premium cost compared to a bottled beer or cooler.
Go wild and enjoy your late teens/early 20's and ignore all these sour OLD grumpy B*st*rds
