So my initial review of Sumac was 4 shiny stars due to the excellent tasty food. Since this early experience I've visited this restaurant a number of times when they have been busy and as a result of my experiences I must update my review.
The food at Sumac continues to be terrific, what is far less than terrific is the system the restaurant has in place for order taking and seating and the owners attitude. When you arrive at Sumac at a busy time they do not allow you to secure a seat before ordering. Therefor you are stuck waiting in the line to order with no idea if a seat will be available for you by the time you get to the front of the line. You also have not idea if the people in front of you in the line are there for a table or for takeout. So the result is that you may end up waiting in line only to find out that there is no space for you to sit and there are a bunch of people standing around waiting for tables to open up.
On a number of occasions I have seen or experienced the owner treating clients with an impatient and rough manner which is a real turnoff to me.
I hope that Sumac figures out how to resolve these issues and provide great customer services so I can go back to enjoying their delicious food.
