As far as the $7.77 steak and shrimp dinner goes... I recommend getting it medium-well done. I get crap for ordering well done steaks, but the chef's at Mr. Lucky's know how to keep it moist and yummy. While I was enjoying my cooked steak, everyone else was chewing on some bloody meat. hahah Also, I do not recommend the mashed potatoes!
Other than what I've just said, this place is pretty standard. Cheap prices, good food, good service! With the money you saved here, you can go spend the rest of it on booze!
