Have been twice, once just after they opened and onceca little later, as a second chance. We tried it again because we figured the staff was busy working the opening kinks out the first time we visited.
The takeaway: if you have time to kill, this is good food that might be worth the wait.
The service on our first visit was slow but the food was good. Took about 15mins to get coffee and another 35-40mins to get food to the table.
The second visit: it took the staff 20 minutes to get coffee and ask us for our order. It took another 35 minutes for the order to actually reach our table; 55min wait for food . Nothing crazy, we're talking an omelette and some pre-made "just heat it up" food. The pre-made "just heat it up" food was refrigerator-cold in the center and the omelette had the wrong meat and the wrong veggies.
The coffee was decent and I might have consudered a third visit but there is an actual (and good) coffee place just a few storefronts away and they serve breakfast sandwiches.
