1. I want to come over for dinner. OR I feel like come over fo dinner. "I want to come over for dinner." You would use this is you are close with a person, for example with Family. But a more polite way to say this is using "May I come over for dinner." 2.I want to try the new Thai restaurant. OR I feel like try the new Thai restaurant. Either of these two sentences will work. But in the second "try" should become "trying" "I feel like trying the new Thai restaurant." 3. if it's OK with you, I want to talk about this some more tomorrow. OR if it's OK with you, I feel like talk about this some more tomorrow. "If it's ok with you, I want to talk about this some more tomorrow." Using "want" expresses the desire to talk again. 4. I want to meet for a drink. OR I feel like meet for drink. Same as the Thai question. Either are acceptable but "meet" should become "meeting." Just remember who you are talking to and what form of politeness should be used.
