Wow what a place! I normally don't get excited over sub places, and there are the run of the mill places you can find in any mall with nothing special food such as you get at the large chains. I have come to expect that from sub shops.
Prior to going to Dave's my favorite sub place in Cleveland was Grums. When I get back to the Cleveland area if I am going to a sub place I usually go to Grums. Both Dave's and Grums are great however there is no seating in Grums and the location is on Coventry.
I was in Chagrin falls and wanted a quick inexpensive lunch so I went into Dave's Cosmic Subs. When you walk in the decor takes you back to the 60's with rock posters everywhere. However that's not why you go there, you go there for the food and I can honestly say it was outstanding.
The bread is what makes their subs special and they make their own daily. You also will find sandwiches you won't find on any other menu. I am a vegetarian and there were quite a few selections. Their customer service is outstanding! The people at the counter were friendly and would give you suggestions if you needed it. Next time I am back in the Cleveland area I definitely will be back
