I believe it is a popular bistro at night, but I experienced it as a Sunday brunch venue. It happened to be an extremely wet Sunday and although we had booked a table it was so busy that we had to wait for a good half an hour, fortunately undercover.
An outside table eventually did become available and despite the elements we grabbed it as we were all starving. To their credit, the waitresses were extremely helpful in ensuring that we were served quickly and were warm enough. This great service continued throughout the meal. Unfortunately, we missed the breakfast / brunch cut-off which occurred at 12pm, which we found slightly unfair as we had booked the table for 11.30am and had been waiting since then.
Not too much of a worry though as the brunch menu was diverse and we all found something to tuck into. I had the leek and herb omelette which was excellent. There were certainly no complaints from anyone at my table of six. It is clear that only top quality ingredients are used here.
