Rhubarb probably possesses the best ambience in all of Leamington. Having been a visitor on and off for 10 years or more, I have always wanted the place to succeed. The interior is dark and eclectic, with a really warm and welcoming atmosphere. The staff are knowledgable and friendly without being 'in your face' all the time. However a criticism is that the quality of the food swings with each change of chef (which for some reason seems to happen too frequently), from great to bland.
At present the food (both flavour and presentation) ranks highly, perhaps amongst the best in town.
French chef Christophe (formerly of Wildes, where quite rightly he enjoyed a large and loyal following) has taken over the tiny kitchen and is serving excellent dishes, beautifully crafted and presented, absolutely full of flavour. Prices are keen and the menu is long enough to satisfy most pallettes, short enough to keep the quality high. Good wine list at fair prices too.
If you've not experienced Christophe's cooking, or even been to Rhubarb before, I commend you to try it, perhaps sooner rather than later. I am sure you won't be disappointed.
If he stays, watch the rankings of Rhubarb shoot up the 'league table'. However, the history of Rhubarb and chefs here, suggests that might be quite a big 'IF'. I keep my fingers crossed. The ambience that is Rhubarb and the quality of Christophe's cooking, are a perfect combination.
