I have been to marthy's kitchen several times. The food is very good, even if the prices are skyrocketing, but the service is just bad. The ambiance is nice but often overcrowded and very uncomfortable. Concerning the service, Once we waited 30 mins for a coffee and after that 1 hour to get a simple omelette and then the waitress repeatedly forgot to bring us bread and salt & pepper, despite our reminders. Eventually we didn't want to tip so we gave the exact amount owed. Surprised, the waitress said 'the tip is not included'; we replied that we knew but we didn't want to tip and she started saying that we had to. The moment was so embarrassing that I personally won't go back again. A pity because the food was good.
