My family and I have been going to A1 for the past 5 years and we have always received excellent food. A1 is mainly a takeout place in my opinion because it has limited seating but the food is consistently good.
The prices are reasonable as well since they charge for curries by the container and naan and roti is separate. They also sell indian sweets by the pound and they have a large variety during Diwali. They offer snacks as well such as samosa chaat, aloo tikkis, bhel puri, and pakodas.
The service is fast and you can order and have your food within 5-15 mins tops. If you're ever in Scarborough and you're craving good Indian food, I urge you to try A1!
