Rovi is the newest branch of the Ottolenghi chain, and is focused on vegetables, fermentation and grilled food (their description, not mine). We decided to go somewhat last minute, and managed to get a table (there is also seating at the bar for walk ins).
The menu was pretty much as described and I would say close to 70% was vegetarian or vegan. We only ended up ordering two non-vegetarian dishes, one being a squid and lardo skewer, the other being a cabbage dish with dashi and anchovies. There was a memorable celeriac shawarma, fresh radishes (which reminded me of those from the Clove Clubs), leaf and stem tempura and peppers with polenta. Peas and broad beans were served in their pods, having been grilled in olive oil, garlic and chilli; this was a very clever dish as we were instructed to eat the peas and beans like edamame, and the result was that we got the taste of the oil, garlic and chilli alongside the freshness of the peas and beans inside. For me, these and the cabbage dish were the highlights.
I had an apricot clafoutis with fig ice cream for dessert, and my dining companion has some small and perfectly formed ricotta doughnuts.
Service was a touch confused at the beginning, but they had only been open a week; once we got our orders in the food came pretty rapidly and I would expect this to continue to improve as they get into their stride. It was a touch expensive but not overpriced.
Overall, we are happy to find another good restaurant in the area. It was already pretty busy and so hopefully, given the backing of the Ottolenghi reputation, this is here to stay!
