This is the home of the mediocre sub. People like it in town because it is somewhat eclectic with the psychedelic paint job and rock memorabilia. For the price, you're really getting ripped off. Let's take a closer look.
First, Dave himself is a complete jerk. He loves himself more than just about anybody I have ever met. Check out their website if you don't believe me- it's all about him. If he is working in the shop, you should just turn around and go somewhere else. He once got into an argument with me over whether I ordered unsalted or salted chips for my take out order. He actually started yelling at me about it- then when he read the order and it said SALTED chips, he started to scream (and I mean scream) at his staff. Get a life, Dave.
The bread these subs are made on is ridiculous, in a bad way. It's got good flavor, but you will regret it later when your mouth is torn to shreds. The ingredients used to be top notch, but it seems as though Dave has moved to some less expensive stuff these days. Alesci's in Solon has better sub sauce than Dave's Cosmic Sauce- so does Grum's (even the crappy one one miles road.)
All-in-all, for the money there are a lot of other places you can go in town and get a good sandwich. No need to burn your hard earned cash by giving it to an a-wad like Dave.
