With lack of information, I cannot really suggest specific business ideas for you. A business is not just about looking for what's trendy and what's hot these days, then going into that direction. You're bound to fail if you do not have any knowledge in running that business.
To help you decide which one is right for you, think of people's needs and wants that you can meet...something that is related to your hobbies and interest (example: photography, cooking, gardening, fashion) , or something you have the know-how based on your skills/abilities (e.g. Silk screen printing) and/or education (e.g. graphic design artist). If it's just a "me-too" business, you need to innovate and think of ways to differentiate your product and services from the rest of competition if you want your business to last.
You can go with a food cart business for a start since somebody has already done the product evaluation, market study, ROI evaluation, etc. The only problem is some of them requires such a huge cash outlay and the contract usually expires after a certain period (say P300k for 3yrs only). There are also many competitors in the food cart business; product differentiation and location are major considerations.
