I visited this square area which is dedicated to all the food truck businesses at the meetup described time. There are around more than 50 truck restaurants doing business in this square. Majority of the businesses here serves fast food, coffee and fruit drinks. This place gets crowded during the weekends (Friday and Saturday), especially during the evening hours. The car parking capacity is spacious and can easily accommodate more than 100 cars at a time. I did find few parking spots reserved for disability customers and all the entrances of this square area supports wheelchair/stroller accessibility. Live music is played here during the evening hours (Mostly, Arabic and English music) and the businesses here offers both the dine-in and take away options.
I have added the names of the food truck businesses which were missing on the google maps and also added the menu, recent photographs of the businesses and other details (Whether the business accepts card payments, Restaurant type, working hours etc.). Here are the photographs of the food trucks taken during the meetup.
P.S: Unfortunately, I was the only one during the meet-up, Iam expecting more local guides from Al-Khobar participate in the future/upcoming events, So that we can highlight more attractions, Places of Interests and food courts from this beautiful part of Saudi Arabia.
