el arroyo used to have awesome margarita specials for happy hour. if memory servers, $1.50 during happy hour. but that was a couple of years ago. now they have raised their prices and they are alright.
i was at hula hut a few saturdays ago and was extremely unimpressed by their margaritas. their food has never been great and now the margaritas???
i generally prefer frozen standard lime margaritas but the watermelon margaritas are pretty damn good. i'm not a fan of strawberry or mango margaritas though.
Midori is melon-flavored, so you won't find it in an appletini. Looks like it should taste like green apple, though. Midori margaritas rock.
Davenport Ranch is the neighborhood around Austin Country Club. Davenport Village is, I think, the name of the shopping center right by the entrance to Austin Country Club where the new Maudie's is located. It's been pretty crowded when I've been there, but you can almost always get a table right away if you're willing to eat inside.
