There are better alternatives in Vernon and Manchester.
i agree that Rein's is good for where it is but wouldn't aurvive where real Deli is understood and appreaciated.
About a mile from Reins, however, is a BBQ joint called Little Mark's www.littlemarksbbq.com
It's about the best BBQ in CT which isn't saying much but they have multiple sauces, good pork and very good ribs.
Suffice to say that Little Mark's is better BBQ than Reins is Deli.
Then, as reported, there's the Shady Glenn...about four miles from both and unique, incredible burgers.
A bit further on, in East Hartford on 603 Burnside Avenue, is a wonderful jerk chicken and pork takeout called "Peppers, Jamaican bakery"...delicious CocoBread (Bimini Bread) and a great pig in a blanket made with cocbread called a cocobite.
All are close to 84 and ez on and off.
It all depends on what you're in the mood for when you get off the highway
