Covent Garden is a pretty great area to work, but I am often at a loss when it comes to lunch options. Decent sandwich options are few and far between and you would be hard pushed to find a good feed in and around the fiver mark. It's so bad that I have even started making my own lunch (cue exclamations of shock)
Taro is a beacon in this wilderness of mediocrity. Their lunch menu is a most bargainous £7 (eat in, cheaper if you take away) and contains enough food to keep you fueled for the rest of the day. In the bento box meals, you get a drink and a bowl of above average miso soup to start, and then a bento box packed with your protein of choice, as well as containing an assortment of other treasures.
Opting for a chicken teriyaki box, I had some sesame bean sprouts, some pickles, a dressed salad, some edamame, a little potato salad and a generous portion of chicken and rice. Best of all, it all tastes pretty great.
I've been working in Covent garden for about a year now and I don't think you are going to find much better food at much better value in the vicinity. There are many choices round here, but few I would proclaim as favourites. And with a logo which has a striking resemblance to yours truly, how can I resist.
