Feels like you're going back in time, when walking inside. The service and sandwiches were excellent! So glad I stopped by.

Friendly staff, very good food, authentic old school.

My dear God. This place is a literal disaster! I don't know if they've just given up because of the competition or what , but, it's dirty, outdated, and the woman is very rude behind the counter. Yelling the prices from the back room and arguing with the man working the register about the prices, never again. Tried to throw them some business out of respect as a long time customer, but I have my limits. Yuck!

quick efficient service with friendly staff

One of the all star delis in the area. Although if the younger staff prepares your food you might be in for a different experience. The older folks that work there hold themselves to a higher standard and have years of experience making the sandwiches and food a 5 star experience.

Breakfast sandwich portion was minimal. $5 for a bacon egg and cheese.

Hearkening back to simpler times, much of the decor of this neighborhood deli has remained charmingly unchanged as ownership has been in the same family for generations. This is truly a place where the owners and staff will get to know your name. This is a regular stop for our breakfast sandwiches or lunch.

Good food, enjoy their daily specials.

The Mountainside Deli is a charm! During lunch rush, it's worth the wait. My favorites are the hot turkey sandwiches, italian subs and french onion soup. Other daily specials that are great are the meatloaf, meatball subs and the extra special german potato salad. (You should probably call ahead if you want a lot of that potato salad! It's popular!) Now that I've moved out of NJ, the Mountainside Deli is missed. May have to take a trip back, just to get a great lunch!

There still is charm and friendliness after all these years. I recommend anyone patronize this deli whether ordering for oneself or for a party.

Great local spot for a quick lunch. Picked up 1/2 a Turkey and Swiss Sub, Diet Coke, and Chips for $10. Food was delicious, service was fast, and entire staff was wearing masks. Recommend stopping by this place if you're in the area.

This is a neighborhood gem. Italian sandwiches are incredible and they make a mean bacon egg and cheese. Staff is always friendly!
