Any Suggestions Please

My mom is coming for a visit today.. and tomorrow my b/f and I want to take her and her b/f out for dinner..and maybe to some cavarans for a tour...just some fun things for her short visit..anyway..my dilemma..is Im very new at this .. and my b/f has suggested to take them to "fire mtn" for dinner... which to my dismay is a buffet style dining facility..  Is there any suggestions as to what I should eat..or should avoid...as to not fall flat on my face with the calorie counting..

A little background on this.. well my mom has been heavy the majority of her life.. when my father passed away when I was 18 (Currently im 29) she went on this craze  ..walked..dieted..was very determined..and was successful..she lost an incredible amount of weight..then when she started dating her b/f she got back into her comfort zone and gained.. some (not all) of the weight back ..well just recently  well with the last year she got fed up again ..and went to WW and lost weight again..the thing is .. and I know she dont mean it.. ( I have the best mom in the world) is that when she starts this.. she kinda gets a little rude with me.. making snide remarks about my weight and so on.. I think she doesnt mean to be rude..she thinks that if she does this it will "kick me into gear" i guess..she even tries the jealousy card..flahsing her new "skinny clothes " and things..Im very proud of her..but would like her to feel the same about me.. so she is coming here.. and of course im only 4 days into this so there is no real weight loss.. but I dont want her to know Im doing this..cause when she sees me again it will be near the holidays..I wanted to "suprise" her with the new me..but I dont want to go to this restraunt and lose control either.. plz help!  *thank you in advance...hugs* Vee

I edited ..for space reason...

well day one of moms visit!!! We went to fire mtn tonight... .. I was so stressed over the whole eating thing.. nothing really is that good at a buffet place EVERYONE knows that.. so I had a hugggge plate of spinach leaves.. I messed up with the basalmic viniagrette though...  then I ate from the bar..but had only cabbage..broccoli..grean beans..corn and so on.. I did go over by about 400 points.. but all my letter grade (if that matters) were As &Bs  because of the type of food I ate.  I did have an ice cream..not to much though.. i messed up with the cone though..those are aweful with the calories *sighs* .. so there was some oversights..but I stayed close to the zone of 1400 as possibe..and amazing enuf my burn meter still out ranks the eat meter..thats good right?  Please any feed back on this...at all????/

HEY! HAPPY SUNDAY!  Well I dont seem to get much of a reply from anyone on here.. Idk..guess I thought it was more like a chat where I would hear from someone daily..well none the less..its sunday and my mother is making the journey back home.  I made it through the visit.. I started this on July 21 @ 191 ..and have lost 4lbs.. well we wanted to dine and entertain my mom and her b/f while she was here for her visit..and we did..and all along  I was scared as everyone knows how dining out can be.. but  I made..well the best choices that yu can make when you go out..and then we had pizza night.. UGH..can I win??!??.. so I had two slice :O I was like OH HECK I DID NOT??!! but.. I was sooo worried I kept weighing myself over n over at various times... (again this morning) and because, even though it was a poor choice, I burn more calories than I consure.. I only gained .4lbs.. I didnt want to gain any..but am thankful for the least amount of gain...   so if I can get the .4 off.. I plan to make better choices..as I dont have guests to entertain all the time.. so im not always going out.. and not dwell on past disappointments.. and continue on a successful journey.. many blessings as you do the same! *hugs * Vee
