I am 1 for 2 at Lamp. The first time I went, I sat at the counter had quick service and great food. So, I decided to bring my wife and daughter with me and the encounter was less than memorable. Yes, the food was good, but the service was... really awful. It was 7:30 pm on a weekday night and a light crowd (save for a table of six nearby whose noise was deafening). With many empty tables, we were seated in the corner next to the restrooms and the rather loud diners who lingered long after the bill came. But, hey, that's their prerogative.
The food was good but we were greeted by two servers--one plus a trainee. There were long gaps in service during which our apathetic servers vanished or chatted with other diners. Our salad order was delivered incorrectly and all of our food pretty much came at once. And then our service pair vanished again. My wife had to go to the front of the house to get a box and our bill as to not prolong our stay.
Lamp is in a spot that has had quite a bit of turnover in a shopping center that resembles a modern day ghost town. I was pleased after my first visit to see a new, exciting dining establishment come to our neighborhood. They best fix their service issues or be the next in line to come and go from North Pima Road.
