My family and I have been going to Shiki in London since I was young. There are not too many Japanese options in London but I find their food quality to be more consistent and has a good variety for a la carte.
For a...recent family dinner we ordered Sashimi appetizer, soft shell crab, shrimp & veggie tempura entree, Hokkai Don (spicy salmon / Ikura on top of rice with cucumbers) and Sake Chazuke ( grilled salmon + rice, with green tea to be poured in). We also originally ordered Tonkatsu but unfortunately the waiter forgot to add in our order, we didn’t bother to order it again as we were full from everything.
Out of all the dishes Hokkai Don was my favorite. If you ever go during lunch, they have a bento called Shiki Special that is a favorite of mine as you get soup/salad, small sashimi plate, a bento with tempura/sushi/chicken/fish + dessert. Great deal for approx $18.99. Lastly, due to covid I recommend making reservations as it gets filled up quickly at night :)More
