We went to Casa de Isaac last Spring and liked it, although on the night we were there, the air conditioning was dripping on our table (and in our margaritas) from the ceiling. Because that grossed a few of the girls out (and frankly me too), I can't get them to go back even though everyone at the restaurant was happy to move our table and replace the drinks.
I didn't realize that Hot Tamales was bankrupt. Like I said, we haven't been there in a long time. Unfortunately, the website you linked doesn't work.
I am hoping that someone has been their recently and can help us out. If not, maybe we'll look elsewhere.
