Staying in Piccadilly, working in Hayes during the day.
Recommendations for great food, prefer not the fancy smancy types. Everything from street food to bistro, gastro pub, etc.
I can travel some via cab or train, especially for dinner.
Anyway, a variety of suggestions for all kinds of cuisines and great bars to get a pint. Nothing touristy. Just good food is important. And something representative of the local food scene.
