Betty's is just fine for what it is: a dive bar and local watering hole. Their beer selection is pretty great. The food is totally mediocre. I tried the steak and Guinness pie last night, which was pretty bland, but did the job. Their nachos are run-of-the-mill. I've been turned off from ordering the burger since a friend of mine once did and found not one but two hairs in it--bit of a deterrent!
My softball team used to go here after games sometimes, and in that respect it's totally fine. Group beers yay, dinner nay.
