I go to Grilli's just about every morning and no longer have to say what I want, they just know!

I worked in East Islip a couple of years ago and I ordered from Grilli’s daily. Covid-19 descended on the earth and after 17 months I have returned to the area and to Grilli’s. This family is super good.… Always greeted with happy people. The food is delicious. The Macaroni, Coleslaw, and Potato salads are HOMEMADE!!! They have Linden’s Butter Crunch Cookies 😋 I recommend Grilli’s to everyone. Get off Sunrise Highway get breakfast and head back out-I’ve done that.

The best breakfast and lunch sandwiches EVER. Everyone is always as friendly as can be both on the phone and when you're there. Truly a neighborhood gem. Makes me proud that they are a part of Islip 😊

Grilli's catered our daughter's Baptism in December. Service was amazing, including the delivery and set up. The food was great, both heroes and hot trays! Most of our guests came up to my wife and I raving about the food. Fantastic all around!

We came here on a Sunday. Google maps says the place closes at 4pm. We get there at 240 and they apparently close at 3. So after being told it was no problem to make sandwiches that weren't on the grill, we got a buffalo bill and Mikey g. Both sandwiches are listed that they come with lettuce and tomato but, didn't receive it on either sandwich. The Mikey g didn't come with bacon and the buffalo bill didn't come with blue cheese as advertised. So we basically got bread with cold cuts and chicken cutlets, for $20. Waste of money.
