Parked right in front of the restaurant (located at the former Boston Market corner area facing Central Ave) at 4:00 and had no wait to order at the counter. The kitchen and cashier section are more cramped than the Fashion Square location. All unoccupied tables were clean, including the plentiful picnic tables outside. Water from the condiment table was chilled, and there were plenty of cups. My small single-item order was completed within a few minutes.
Single 'Mallow Monsoon: Far superior to s frosty, and also better than a Dairy Queen blizzard. The chocolate and vanilla custard are swirled but not completely blended, but the overall flavor leans strongly chocolate. I could not really taste the marshmallow sauce. The chocolate truffle cookie dough were super rich and reminded me of fudge brownie pieces. The sugar cone cookie pieces had a fantastic crush, and provided a great contrasting texture.
Shake Shack may be cost a little more than its competitors, but their quality is a step above as well. My concrete was $4.98 after tax.
