Cascadas Mexican Restaurant is located at 424 Main Street in Beacon and we've been meaning to try them for some time now. Twice we went by and they were crowded and once we stopped on a night they were closed. Well, we finally got there and it was worth the effort.
Inside it is small, seating thirty or so including the bar, but there are tables outside. It is clean, uncluttered and has mexican music playing. After looking over the menu (not a huge menu) I got the shrimp tacos at $12.95 and Teresa had the enchiladas at $9.95. We stuck with water (there was no ice in it) and we were brought a bowl of nachos and salsa. The salsa was good with just the right amount of heat. You only get one round though, more costs extra.
My three shrimp tacos were quite good. The shrimp tasted fresh and there was ample fresh avocado on them. They were a bit dry until I added the delightful spicy avocado on the side (it might have been meant for the enchiladas) and that added just the right kick.
The food was really good, the service so-so (our waitress seemed to be infected with a touch of ennui), the ambiance was okay and the prices were good. Overall quite nice and we will go back. They have a website for more information.
