I suspect that 'Posh's' comments be taken with the large degree of scepticism they deserve - joined the forum the same day as their only two posts.
I've had food from Lemon Tree twice, eat in first, based on the early reviews on this forum, and grabbing a takeaway after an extended evening frequenting local purveyors of refreshments.
Dining in was great; no sign of any sleaziness, but a healthy interest from the manager about feedback for the quality of his food (v. good). In fact, the young lady that served us for the evening could hardly have been described as confident, however her apparent lack of experience was more than offset by her charm. Still good service for the takeaway, although found a couple of our meat based dishes a little greasy (should probably be ghee-ey?), but still tasty.
Planning to go back next week, as there is still not enough positive feedback about Gurkhas to consider it an option.
