    We just discovered this place a few weeks ago and love it! We first went for Brunch on a Saturday with 8 people and one child! Darcy, was truly amazing! She dealt with my high maintenance family and gave great hospitality!! So then I took my youngest son there last night and we sat at bar and had Jordan and he was amazing! As I am in service industry, I make it a point to remember names ! These two people were great! The food was also good! I had Haddock Piccatta, and my son had Salmon. Both dishes were delicious! My son got crème Brûlée and said good, but it had basil and as we are both in industry, the basil should have been taken out. Drinks were great too! Do we both gave this a great experience!!!!
