Eateries from Bangalore to Coimbatore - Indian Roadie Preferred Cafe

The roads are really good, there is nothing to worry about. Its a flat 5 hr journey.

You shall find A2B just before and after Salem.

A2B

One at Rasipuram just after salem.

Sai Sangeeth just before Thoppur tollgate is better than A2Bs around there.
Crossing Salem is no more a difficult proposition because there are 3 flyovers that helps to cross the city of Salem in 10 to 15 minutes.
Good food joint is Sree Saravana Bhavan
Vangli Towers National Highway 7, Avathanapatti, Tamil Nadu 635101.

Beware of multiple imitations near Sree Saravana Bhavan, go to the exact location. There is a break in median near the authentic brand.
Sai Sangeet is good for North Indian items. After Salem before the next toll gate there is another branch of sree saravana bhavan. This is good for parking and toilets. However, items in the menu are limited.

Another excellent place but just 80 km before Coimbatore is Rukmani Ammal Vegetarian Restaurant,
Erode, Tamil Nadu 638052

There's Junior Kuppanna also for non veg in the complex.

Nothing to worry. The roads are good.

Watch out for barricades all through the way.

Eateries.... You will find plenty of decent options on the way. To be precise at least one every 20 or 30 kms.

An early morning start from Bangalore will help reach Coimbatore in good time.
