I want to start by saying, this is just one opinion and maybe the things that bother me, will not bother you.
I thought the food at Mamasita was delicious, but I don't think I will be going back and here are my reasons-
I don't mind waiting at all, and am willing to wait an hour for dinner -but- I would like to sit down and have a drink, or I would be happy to leave a mobile number and go sit somewhere else. We were first in a very long line that is along a stairway, so it isn't easy to sit down. Then we were told we could wait by the bar, which was about three or four layers deep with people, but when we said we didn't want to eat at the bar, then we weren't allowed to sit at the bar.
Almost all the seating in Mamasita is bar style tall stools, which aren't so comfortable if you are short, and even if you aren't sitting at the bar, some of the other seating is counter style.
And finally the music is very loud.
In a different setting, I would go back for the food.
