Good diner in midtown east - 30s or 40s?

[realbigfoodie]

My dad is in town and he likes diner food and delis, especially since he is a native new yorker who doesn't live here anymore. I am looking for a good place to go near his hotel which is low-key, not too expensive, and has really good eats. Unfortunately my normal go-to sites (menupages, yelp, etc) aren't helping out too much. Any good suggestions? Thanks!

I love Sarge's (it's located on Third Ave. between E. 36 & 37 Sts.--not Lex and 33rd). Sarge's has great deli and comfort food.
