This deli is an absolute gem! The new ownership has completely transformed the place with an incredible renovation — it looks amazing, super clean, and now even has comfortable seating to enjoy your food.
The sandwiches and paninis are outstanding — fresh, flavorful, and made perfectly every time. You can really taste the quality.
The new owners are so friendly and welcoming, and the service is top-notch. You feel appreciated the moment you walk in.
Definitely a must-try if you’re in the area. Highly recommend!

I had not visited since the new owners took over! Big mistake! Absolutely the most delicious in house roast beef! And the rye bread was incredible. Such an amazing transformation from the previous owners. Best deli in the area!

The food was ok, nothing special, I had a cheesesteak and we also ordered a regular Italian type sub.

Got a delicious Cuban sandwich on a recent visit. Drove over to Echo Lake Park to enjoy on a beautiful day. Easily could have shared this sandwich with another person! Highly recommend!

I use to eat here 20 years ago. It use to be good. Now it has new owners and it went downhill. I ordered a simple chicken cutlet sandwich and the chicken stunk! Like old. There also no variety of chips and snacks. Wtf happened
The mountainside deli is under new management and it’s better than ever. They have so many new menu options and they’re very delicious. We enjoyed the vegetarian Panini and the pastrami sloppy Joe, which was very authentic to New Jersey and delicious. They also have more fun menu items like tacos now. we got the classic rice pudding and it was perfect. It was all reasonable prices and the new owner is so kind really wonderful service. I’ll be returning.

Words cannot describe how disappointed I was to open this from the wrapping. I am not exaggerating when I say this is the SKIMPIEST taylor ham sandwich I have ever gotten. And it was a ghost town when I went in there- probably for obvious reasons. Never returning.
Everyone is great

This is a neighborhood gem. Italian sandwiches are incredible and they make a mean bacon egg and cheese. Staff is always friendly!
EDIT: 6/23 new owners if you’re reading this please don’t change the Italian sub or the German potato salad. Mountainside and Westfield thank you ?
Excellent place to get grill chicken sandwich!
