Give Lecoq a shot and take a look at their wide selection of bentos, super salads, party platters (with sake, gin, soju options) and yummy side dishes (hei zho, firecracker chicken, fried mushroom nuggets, mentaiko fries, luncheon chips etc) Apart from the hearty proteins they have, they also have a comprehensive list of keto friendly (shirataki noodles/cauliflower rice) bentos!
