Depends of course where you are and what you’re after but:

Mii and U up near the A5, great and cheap cafeteria style oriental food is brilliant. Don’t let the fact it’s on an industrial estate put you off. Half of it is also an oriental supermarket. Brilliant place.

Not far down the road is MK11, great for wings Wednesday and have all sorts of other deals on other days (burger and a beer etc). The open mic night and quiz are also great there.

For other cheap eats the Wetherspoons (the one down towards the station) is the better of the two. Moon under water is less pleasant.

Just over the road is brewhouse which again does reasonably good food, higher quality than Wetherspoons.

For better pub food wavendon arms in wavendon, the black horse in great linford and the swan in Woburn sands are all good quality places (owned by the same chain). The swan at Salford is also very good and owned by a different group so nice for variation. Likewise the carrington arms in moulsoe is very good. The bull out in Olney also upped their food game massively after it burnt down and was rebuilt a few years ago. As mentioned previously cross keys in woolstone is good for both food or a quiet drink. The wheatsheaf in bow brickhill also has great food. As does the old red lion up in great brickhill, the food here is brilliant and the terraced garden out the back has amazing views on a nice day.

Out in Newport pagnell is pin petch which is a brilliant Thai place.

In Bletchley is a small family run Portuguese place called house of chicken. It’s phenomenal and very authentic Portuguese food cooked over charcoal and very cheap. Absolutely brilliant spot and the couple that run it are lovely.

The best Chinese I’ve found anywhere is the old Shanghai in Olney. Although foodie house in Woburn sands does a reasonable takeaway.

For Indian restaurants I’d say the Jalori in Woburn sands or Maya in Olney, or the four pillars in Olney. All very good.

At the top end is Paris house on the Woburn estate. They do seasonal tasting menus with wine pairings. Not sure whether it’s Michelin starred or Michelin recommended but it’s absolutely stunning and in a beautiful setting.

For pubs for a drink rather than food ( I know you didn’t ask this) but I’d say wharbler on the wharf close to the centre, the Royal Oak in Woburn sands, the fir tree in Woburn sands, the barge in woolstone, the white hart in Sherington, the coach house in Newport pagnell are all great.
