Western suburbs of Boston
I work about a week a month near Newton/Wellesley line and am always looking for good places to eat in Newton/Waltham/Wellesley, etc. Doesn't have to be fancy, just good. Often dine alone so places that are comfortable that way are good too.
Not sure what time of day you are interested in, but these are both good lunch places, though they serve dinner on some nights. Also, there is The Bistro Cafe at Nordstrom at the Natick Mall, as well as Sel de la Terre. I have not had lunch at SDLT, but have several times at Nordstrom. Their nicoise salad with salmon is a favorite of mine.
Gourmet Decisions Cafe & Grill
7 South Ave, Natick, MA 01760
555 Washington St, Wellesley, MA 02482
How about Buff's Pub in Newton Corner? Good food plus friendly waitstaff/bartenders and patrons.
In Waltham, I like:
Beijing Star for Nothern Chinese (their lamb soup is incredible)
Bann Thai for Thai
Elephant Walk - a bit more upscale
In a Pickle for cheap, diner-type breakfast/lunch; or weekend brunch
Thai Thai Kitchen in Newton center has decent thai food. It's more of a take out place but it has no frills seating too for a quick bite. I see alot of people dining there by themselves.
Blue Ribbon for a pulled pork sandwich should not be too far - rest of the bbq there has taken a nose dive in recent months imo.
I am digging Tacqueria Mexico and Little India buffet in Waltham recently for lunch.
