My family and I are renting a flat on Sandwich Street in the Bloomsbury section of London. I have reviewed various websites and am somewhat familiar with the area, but would love recommendations on inexpensive places to eat within walking distance of the location mentioned above.

North Sea Fish Restaurant is on Leigh St. It is a college area so there are lots of cheap eating places around.

We really liked the Busaba Eatthai on Store Street. It's Thai, served family style.

Drummond St by Euston Station is a street of cheap and good Indian restaurants (largely vegetarian). When I worked in the area it was a regular destination.

There's also a street of Woburn Place - Flaxman Terrace which has some good cafes in it, and a on the other side of the Euston Rd you have Chalton St which has some good cafes and a really good gastropub - the Somers Town Coffee House.

You are practically on the doorstep of North Sea Fish restaurant(best fish ever) and a stones throw from Chutney's, 124 Drummond street, or Ravi Shankar at 133, as apposed to Chutney Mary's in the Kings Road.
Walk a little farther down just past Russell Square, turn into Cosmo Place and then into Boswell street and you may find a little restaurant called Milli Pini. It's years since I went there so who knows? Also, what about The Sun Tavern in Lambs Conduit(off Great Ormond street) for pub grub!
