My first time to Suppa's in Billerica. From the call I made for takeout to the moment I walked out the door, the service was above excellent!! Its so hard to find good customer service these days and this place definitely has it!! The subs we got were delish! The Owner was there and gave me the red carpet treatments and when I explained I had a wheat/gluten allergy he asked what I liked on my pizza and had a pizza made specially for me. Best gluten free pizza I've ever had hands down. Looking forward to my next visit!
