Some of the London threads are getting stale, so I thought I'd add some recent good experiences, and include specific dishes I'd order again:
Dancing Greek Taverna- huge portions of hearty Greek food. I liked the spanakopita, dolmades, grilled octopus, fried calamari, maroulosalata. Will return to try their tyrokefteri and souvlaki in a pita. April 2012.
Abruzzi on King. Love their seared tuna, grilled octopus, local asparagus salad. Down-to-earth, warm service. May 2012.
The Tasting Room. Liked the zucchini latkes, scallop salads (huge value at $13 or$14), salt + pepper calamari. Appetizers are more generous than I expected. May 2012
Richie's Family Restaurant- my favourite Greek omelette in London, and great home fries. May 2012
Places I plan to try in the near future: Green Tea Cuisine, Spring on Dundas, New Tai Hu, Mexicactus, Los Comales and True Taco.
Places I'd like to revisit in the near future: Kantina on Talbot and Bungalow on Waterloo at Cheapside.
Please post any recent good dining experiences you've had in London! ;-)
