Not a foody, stops at certain restaurants, not because of the best food, but for the sake of stopping there the time before. That was certain restaurants got added to pitstop list. Pee would be the primary concern
Indian Coffee House chain - No mallu can travel without them. Run by cooperative societies. Uniform menu and facilities. Most of the employees would be union members, so expect attitude issues. Food would be affordable and good. They would add beetroot to virtually everything except maybe tea and coffee. So expect everything to be purple. Beef omelette, beef cutlet at special over there. My pick would be poori or dosa. My usual stop would the one at Kanjukuzhy. Decent parking. Crossing to the other side is a bit tricky due to undivided highway and speeding stretch.
Hotel Sri Gowri Shankar, near Nagercoil. The only restaurant I would stop when going south into TN, before venturing into NH44. Still itches to stop there when going even farther. Pure veg hotel. Poori Masala my favourite. The new alignment of NH66 would make it obsolete. Traditional but not so busy washrooms. Bakery and juice stalls. Enough space for parking. Crossing the road is a nightmare. One of the narrow and busy stretches of NH66 (old 47) with no road manners at all.
Hotel Aryas - original and duplicate on either side of the highway just before reaching Kavalkinar junction, the last point of civilization years back just before entering NH44. Okay kinda restaurants. Not so clean washrooms. More and enough parking space. Would become insignificant with the new alignment of the highway.
Jaison Bakery - Also at Kavalkinar. This was the only place to fill the stomach during the initial times we (
@vishnu vichu) used to hit NH44. Open 24 x 7. Used to be a small bakery. Grew up over time. Separate section to tea and a vast collection of snacks. Still stops there. No restroom or table service. Umpteen options to fill up the car for the next 100s of the lonely highway (now many eateries came up, but lazy to exit the highway). Would become insignificant with the new alignment of highway. Roadside parking.
Italian Cake Shop - Rivals to Jaison Bakery. Have specialities of nearby towns like Tirunelveli halwa, jigarthanda, etc. A bit modern over Jaison. Stopped buying unpacked displayed bakery stuff after seeing rats running over the display counter. Still worth a try. Again roadside parking, no restroom.
Kovilpatti CCD. The only place we would stop after Kavalkinar. AC great relief when we are on bike in that exhaustive sunny highway. Situated inside HP pump. Can fill both tank and tummy. Washroom will be locked most of the time. The only place that used to accept card payment in those days. Forget about ATMs in that highway. We had to travel till Madurai, exiting the highway with GPRS based navigation some 10 years back to find an ATM to fill petrol to hit back home.
A2B at BPCL Ghar COCO outlet. Only A2B restaurants I have been to. The menu was huge. Food was good. Service was okay. The restroom was good at the gas station. Lots of parking space.
Back in Kerala, if I am travelling via NH66, which I never chose to, would stop at Mother's Kitchen near Karunagapally. All sorts of traditional Kerala delicacies puttu, appam, dosa, kadala, kozhukatta, etc, etc. Roadside parking, but wide shoulders. Great restrooms if you are travelling with family. Best food in that stretch. The only issue is they open up by 7:30-8, by which time I would have passed Alapuzha, else would die in the traffic jam.
When travelling via MC road, only stop would have been the legendary Vazhiyorakada near Kilimaanoor. Again, traditional and native Kerala food, lot of non-veg delicacies, served in banana leaf. Indian-style toilet with big queue in case you happen to stop with a bus party. Lost the charm over time due to the heavy rush. Good for breakfast. Located at a haphazard turn. Mishaps happened before. Undivided state highway and speeding through curve idiots make it a hit-miss affair. Can eat only if you are lucky.
Apart from these usually stops at veg restaurants as veg is comparatively safer when travelling.
