Saw this place on Southern Charm, and had called ahead to buy a GC for it. Cute little place with interesting food choices. We had some chicken salad and a short rib, both great. Owner was very nice. Love the Ion community & we'll be back!

This place is very convenient, as it's very close to my home. It does very well because it is in a nice neighborhood but the prices are exorbitant for what you get. I do like the soups though, on occasion.

I live in the neighborhood and am glad to have this place nearby. The sandwiches and other items are well designed and tasty. You can dine inside or outside if the weather is nice, or take away. But I find the prices here pretty steep for what you get. If their price point was a little lower they'd get a... More

2 words - Turkey Parm! End of Story! OMG this sandwich is good. They have wonderful desserts and other items in the cooler. The seasoned beef with horseradish on the side...awesome. They definitely focus on quality of everything....the flavors are just amazing. If you don't like this place you are probably a fan of McDonald's.

What a neighborhood gem. I met a friend here and had the half salad and half roast beef sandwich. Brought my husband the next day for soup and salad. Small, cozy, with homemade soups. Talked at length with the owner and it's obvious that he's passionate about what he does. Definitely recommend for informal lunch. They also have a menu... More

Limited but interesting fare. Soup of the Day was what got my attention and it was good... a chicken and bean soup with some bite. Line is long around dining times and customers a bit crunchy. Expect to be licked by dogs as customers bring in their slack-leashed dogs in tow. Staff is friendly but when it gets busy, you... More

Located in the Ion neighborhood of Mt. Pleasant, Charleston, this is a family-style upscale deli. You can eat inside, on the sidewalk, or across the street in the little park. Pet-friendly and pleasant, I always annoy watching the neighborhood kids ride by on their scooters or bikes. I had the special, a greek wrap with lamb, feta, sour cream on... More

I absolutely fell in love with this neighborhood. I saw that the Square Onion had very high reviews so I decided to try it out. I had the "Pick Two" with the Meredith and the Mary Hope Salad. I was okay with the $9 price tag until I realized they did not offer just a cup of water and instead... More

Well after my fourth caprese sandwich this month I figured it was time to give them a shout out! When I visited Europe I became very fond of the fresh bread and cheese! Almost daily we would pick up a caprese sandwich on the streets and I was almost convinced to move there for their food alone! Then I found... More

This is a great little place for lunch. They serve salads, sandwiches, drinks and desserts with seating indoors or outdoors under shade trees in the Square of I'On. Great place to meet up with some friends. The food is always good and fresh and the staff is quite friendly.
