Housed in a 19th century Manze's pie shop on Chapel Market in North London, the Seagrass is a lovely little restaurant opening Wednesday, Thursday, Friday and Saturday evenings only & serving fresh and interesting set meals from an open kitchen for a reasonable value. The interior of the restaurant is true to its roots, and has been changed little since the closure of Manze's, with pleasant results.
Your author visited last week for dinner, and had a set three course meal for £30, which sounds like quite a lot, but the results were well worth it, especially given the bring-your-own-drink policy, and the policy of not charging for corkage. The group were especially impressed that when the dietary requirements of one of those present were not catered for, the chef went out to the shops to buy ingredients and made something off menu.
Be warned, however, that for those of questionable self-control, the BYO policy can lead to overindulgence. And if you visit with the same group, come armed with the ability to say no to amaretto.
